Version Description
- Info: This plugin is way more work than expected, please motivate me by giving it a good review and also my trying my other plugins (https://meowapps.com). Thanks a lot for that :) I will do my best to make this plugin perfect.
- Update: Avoid interfering at all with all Ajax/Rest requests.
- Update: Use HtmlDomParser instead of DiDom (this parser is less sensitive to badly formatted HTML). I am also thinking of doing it all with regexp, but let's see that later.
- Info: Sorry for the last bunch of updates, some way of modifying HTML works for some, and not for others, and I am still trying to find a solution which works for everyone.

* Yousuke Kumakura (Attribute filters)
|
| 10 |
+
* Vadim Voituk (Negative indexes supports of "find" method)
|
| 11 |
+
* Antcs (Constructor with automatically load contents either text or file/url)
|
| 12 |
+
*
|
| 13 |
+
* all affected sections have comments starting with "PaperG"
|
| 14 |
+
*
|
| 15 |
+
* Paperg - Added case insensitive testing of the value of the selector.
|
| 16 |
+
* Paperg - Added tag_start for the starting index of tags - NOTE: This works but not accurately.
|
| 17 |
+
* This tag_start gets counted AFTER \r\n have been crushed out, and after the remove_noice calls so it will not reflect the REAL position of the tag in the source,
|
| 18 |
+
* it will almost always be smaller by some amount.
|
| 19 |
+
* We use this to determine how far into the file the tag in question is. This "percentage will never be accurate as the $dom->size is the "real" number of bytes the dom was created from.
|
| 20 |
+
* but for most purposes, it's a really good estimation.
|
| 21 |
+
* Paperg - Added the forceTagsClosed to the dom constructor. Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.
|
| 22 |
+
* Allow the user to tell us how much they trust the html.
|
| 23 |
+
* Paperg add the text and plaintext to the selectors for the find syntax. plaintext implies text in the innertext of a node. text implies that the tag is a text node.
|
| 24 |
+
* This allows for us to find tags based on the text they contain.
|
| 25 |
+
* Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.
|
| 26 |
+
* Paperg: added parse_charset so that we know about the character set of the source document.
|
| 27 |
+
* NOTE: If the user's system has a routine called get_last_retrieve_url_contents_content_type availalbe, we will assume it's returning the content-type header from the
|
| 28 |
+
* last transfer or curl_exec, and we will parse that and use it in preference to any other method of charset detection.
|
| 29 |
+
*
|
| 30 |
+
* Found infinite loop in the case of broken html in restore_noise. Rewrote to protect from that.
|
| 31 |
+
* PaperG (John Schlick) Added get_display_size for "IMG" tags.

|
| 1347 |

* tags, not taking into account that some (non-blocking) tags should close
|
| 1348 |
+
* these optional closing tags. For example, the end tag for "p" is omissible
|
| 1349 |
+
* and can be closed by an "address" element, whose end tag is NOT omissible.
|
| 1350 |
+
* Currently a "p" element without closing tag stops at the next "p" element
